Flash thermography
WebMar 1, 2008 · Flash thermography constitutes the application of a short optical pulse on bulks surfaces, to investigate its subsurface status. The material response (cooling curve) is then recorded using a thermal imager (cooled or uncooled focal plane arrays FPA) to compare the temperature–time history to known, defect-free behavior.

Webcompared to conventional flash thermography were possible. The reason is probably the low irradiance (significantly lower than flash lamps) and low modulation bandwidths of the halogen lamps used [7]. Even if lasers were used, there were only pulsed lasers and only very small areas of a few mm² were examined [8]. WebApr 5, 2024 · In this paper, flash thermography was used to integrate the CW THz results. In flash thermography, photographic flashes are used to produce a heat pulse (transient pulse) on the specimen surface.
